This paper investigates the shaft bow influence on the rotor-stator contact dynamics. For this purpose the rotor is described as a simple Jeffcott model and the stator as an elastically suspended rigid ring. To test the numerical model, except a usual run down analysis, an emergency shut down after the sudden rotor unbalance increase is also analyzed. Numerical integration is carried out by the fourth-order Runge-Kutta method. Two different normal force models for the rotor-stator interaction are analyzed. For analyzed parameters, both linear and nonlinear (Hunt and Crossley), normal force models gave similar rotor and stator responses. To confirm some of the results and to tune the numerical model, the experimental investigation on the test rig was conducted"},{"@xml:lang":"sl","#text":"Poves gredi je stvaren problem, ki se pojavlja zlasti pri vitkih rotorjih. Prispevek obravnava vpliv povesa gredi na dinamiko stika rotorja in statorja. Rotor je v ta namen opisan kot enostaven Jeffcottov model, stator pa kot elastično obešen togi obroč. Za preskušanje numeričnega modela je bil poleg običajne analize zaustavljanja analiziran tudi izklop v nuji po nenadnem povečanju neuravnoteženosti rotorja. Opravljena je bila numerična integracija po metodi Runge-Kutta četrtega reda. Analizirana sta bila dva različna modela normalnih sil za interakcijo rotorja in statorja. Tako pri linearnih in nelinearnih analiziranih parametrih (Hunt in Crossley) so modeli normalnih sil dali podoben odgovor rotorja in statorja. Za preverjanje nekaterih rezultatov in fino nastavitev numeričnega modula je bila opravljena eksperimentalna raziskava na preskusnem sistemu"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-QXUXEY4O","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-QXUXEY4O"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-QXUXEY4O/3fb4d730-b4e2-4796-9f3d-b3c1c76756c1/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-QXUXEY4O/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-QXUXEY4O"}}}}
